Vhf & gps

[Racingfrank7]

Hi all.
Just a quick question.
Can anybody help, there's 3 wires that come from the raymarine plotter to link to vhf :-
Black, blue, white,
Yet the vhf only has 2wires coming from the gps port :-
Red and black.

Does anybody know which goes where please ?
Cheers.

Sorry can't help, but I have found Raymarine service desk really helpful in the past. If nothing comes back on here, try giving them a call in the week?

What model plotter and what model VHF?

Look in the manual to find out which is which. There is no standard.

Bit more info required, what plotter and vhf do you have? 3rd wire could be ground but without more info it's impossible to say.

Book doesn't say.

RL80c and a cobra vhf dsc

From having a read up one isn't used and the other 2 are a positive and negative from the GPS output.
So hopefully get a voltage reading with multimeter

What are you trying to sort out? Is it a GPs fix for DSC?

 

[Racingfrank7]

The vhf should have a GPS fix at the moment it just shows 99999999 on the display and possible the same again
( can't remember now new to me boat and no handbook for vhf ) underneath like this

/ 999999999 tx high /
/ 999999999 ch 8. /

Have you tried looking on the Cobra web site for a manual?

 

[mlines]

From the cobra manual


Bond the NMEA out negative wire to the black
wire of the GPS interface cable.

Bond the NMEA out positive wire to the red
wire of the GPS interface cable

 

[Racingfrank7]

It's more the colour of the wires coming from the boat loom / raymarine / sea talk.
Wires from cobra are red and black so going to take that as + & -
Like I say hopefully multimeter will tell me next time I'm at the boat. Thanks for your help by the way.

From the 4 pin Raymarine lead the white is nmea out neg and blue is nmea out +, the 3rd wire is screen.
Don't confuse this with the other power/nmea lead as that does inputs only.

Spot on thank you.
